dimmer installation

Question

I have Fibaro Dimmer 2 to install and it seems I have trouble to understand instructions.

 

This picture shows my switch box and I have one live wire (brown one), one neutral wire (blue one) and one wire I do not know what is used for (green&yellow one).

I assume that it is used for communication among the switches because these lights can be switched on/off on two different switches on the opposite side of the corridor.

 

I checked brown wire and it has current when fuse is on. Others do not.

 

In all this I have live & neutral wire but I miss load wire which goes towards the bulbs.

 

Am I missing something here?

Hi, what was installed before? A wall outlet? 

Normally you only have ground (green yellow) only when there was a wall outlet. If you don't have a load wire there are 2 options:

1) Install a bypass as load and remotely control a lamp with other module installed at the lamp in the roof

2) install a switch 2, this works without A load wire and remotely control a module

If I was you, I would get an electrician in to sort this as you need to know electrics. Your life is more important than saving money. If you want cheap smart lighting then get the Ikea Tradfri or something similar.

 

The green and yellow wire is normally the earth. In some cases, some people use it for 2 way switching (you need a common) which is a big no no and highly illegal, well in the UK anyway.

 

There is not enough information to advise you if you want to carry on regardless of the safety issues.

 

 

From what you have stated, you have 2 switches controlling one light and only 2 wires for the light switch (live and switched live (brown + blue)). Research 2 way switching on a 2 wire system.
